Permitted Development in Wales – the Welsh GPDO

The General Permitted Development Order, usually shortened to the GPDO, grants planning permission for many types of development without the need for a normal planning application. It covers far more than house extensions: the Welsh Order also includes rights for agriculture, industry, infrastructure, changes of use, temporary uses, telecommunications and other development.

Wales and England started with the same 1995 Order, but they no longer operate under the same GPDO. England replaced the 1995 Order in 2015. Wales has continued to amend and modify the 1995 GPDO, so the Welsh system now needs to be read in its own right.

The Welsh GPDO is still based on the 1995 Order

The legal starting point is the Town and Country Planning (General Permitted Development) Order 1995, which Planning Geek hosts locally.

That PDF is the Order as originally made. It is useful for understanding the structure, but it is not a safe statement of the current Welsh law by itself. The Order has been amended and modified many times since 1995, sometimes by legislation whose title does not mention permitted development at all.

Where a current revised provision is available on legislation.gov.uk, Planning Geek links to that as well as keeping important source documents locally where appropriate.

Welsh GPDO legislation

For day-to-day legal checking, the best starting point is the current revised 1995 GPDO on legislation.gov.uk. That consolidated version should be checked alongside the relevant individual Article, Schedule, Part or Class.

Planning Geek also keeps key source instruments locally so the amendment history is not dependent on external links alone:

• Town and Country Planning (General Permitted Development) Order 1995 – S.I. 1995/418 – the Order as originally made
• Town and Country Planning (General Permitted Development) (Amendment) Order 1999 – S.I. 1999/1661 – among other changes, revoked Article 1(4)
• Town and Country Planning (Electronic Communications) (Wales) (No. 1) Order 2004 – S.I. 2004/3156 – inserted the Welsh electronic-communications provisions
• Town and Country Planning (Miscellaneous Amendments and Modifications relating to Crown Land) (Wales) Order 2006 – S.I. 2006/1386 – Crown land definitions and related GPDO changes
• Town and Country Planning (General Permitted Development) (Amendment) (Wales) Order 2009 – S.I. 2009/2193
• Natural Resources Body for Wales (Functions) Order 2013 – S.I. 2013/755 – updated Welsh environmental-body references
• Town and Country Planning (Compensation) (Wales) (No. 2) Regulations 2014 – S.I. 2014/2693 – relevant to withdrawal of prescribed permitted development rights
• Town and Country Planning (Environmental Impact Assessment) (Wales) Regulations 2017 – S.I. 2017/567 – relevant to the Article 3 EIA restrictions
• Town and Country Planning (General Permitted Development) (Amendment) (No. 3) (Wales) Order 2020 – S.I. 2020/1318
• Town and Country Planning (General Permitted Development etc.) (Amendment) (Wales) Order 2022 – S.I. 2022/997 – substantially rewrote Article 4 procedure, omitted Articles 5 and 6 and inserted Schedule 2A
• Historic Environment (Wales) Act 2023 (Consequential Provision) (Secondary Legislation) Regulations 2024 – S.I. 2024/924 – updated historic-environment references in the Welsh GPDO
• Town and Country Planning (General Permitted Development) (Amendment) (Wales) Order 2026 – S.I. 2026/79 – the latest major Welsh GPDO amendment, with provisions brought into force during 2026

This is a selected source list rather than an exhaustive amendment table. The 1995 Order has also been amended by other legislation, including instruments whose titles do not mention permitted development. The individual Planning Geek pages therefore use the current revised statutory wording as the legal master and identify the important amending instruments where they matter.

How the Welsh GPDO works

The easiest way to understand the Welsh GPDO is in layers.

• The Articles contain the framework and the legal machinery, including the provision that actually grants the planning permission
• Schedule 1 identifies categories of land which affect how some rights operate
• Schedule 2 contains the permitted development Parts and Classes themselves
• Schedule 2A now contains the Welsh procedure for Article 4 directions
• the remaining Schedules contain other supporting and historic provisions

Article 3 is particularly important. It is the provision which grants planning permission for the development described in Schedule 2, subject to the wider restrictions in the Order and the limitations and conditions in the relevant Class.

So a Class should never be read in isolation.

Welsh GPDO Articles

Planning Geek is rebuilding the Welsh GPDO from the legislation forwards. The Welsh GPDO Articles are now complete and include the current statutory wording alongside practical explanation and source links.

The current sequence is:

• Article 1 – Citation, commencement and interpretation
• Article 2 – Application of the Order
• Article 3 – Permitted development
• Article 4 – Directions restricting permitted development
• Articles 5 and 6 – omitted for Wales from 20th October 2022
• Article 7 – Special directions for specified mineral development
• Article 8 – Cancelling or varying directions
• Article 9 – Revocations

With the Articles complete, the next stage is the Schedules, starting with Schedule 1, followed by the individual Parts and Classes in order.

Some Welsh rights match England – others do not

There will be places where the practical answer in Wales is the same as England. There will also be pages where a small Welsh difference matters and others where the two systems have diverged completely.

Planning Geek will not create a duplicate Welsh page simply because a Welsh URL can be created. Where one page can accurately serve both jurisdictions, it can do so with a clear jurisdiction label. Where the Welsh answer is materially different, Wales will have its own page.

That is especially important for changes of use. Wales has its own Use Classes and does not have every English permitted development route. For example, there is no Welsh equivalent of the English Class MA right, and the Welsh treatment of HMOs differs from the familiar English C3 to C4 position.

Article 4 directions in Wales

Permitted development rights can sometimes be withdrawn by an Article 4 direction. The Welsh procedure was substantially rewritten in 2022, when Articles 5 and 6 were omitted and a new Schedule 2A was inserted.

But an Article 4 direction can only withdraw a permitted development right that actually exists. This distinction matters when comparing England and Wales. A lack of an Article 4 direction does not create a Welsh permitted development right which the GPDO never granted.

Prior approval and other conditions

Some permitted development rights are automatic if every limitation and condition is satisfied. Others require the developer to notify the planning authority or obtain prior approval before starting work.

The matters an authority can consider depend on the particular Class. They can include issues such as siting, design, transport, flooding, noise or contamination, but there is no single universal prior approval test.

That is why each Welsh Part and Class will be built from its actual wording rather than using a generic English prior approval explanation.

The Planning (Wales) Act 2026 and the future GPDO

The Planning (Wales) Act 2026 received Royal Assent on 27th April 2026. Most of it is not yet in force. A limited group of introductory and machinery provisions came into force on 28th April 2026 — including Chapter 1 of Part 1, section 42 and sections 407 to 410 — but the substantive new planning framework still awaits commencement. Welsh Government has confirmed that the existing planning framework continues until the relevant provisions and subordinate legislation are commenced.

The new framework is currently anticipated to come into force in October 2027. Until then, the 1995 GPDO as amended for Wales remains the operative permitted development framework. The current commencement position is also set out by Law Wales.

Planning Geek will track that transition as part of this build so that the Welsh pages can be updated systematically rather than patched one at a time later.

Working in England?

If the land is in England, use the separate Planning Geek GPDO section for England. England uses the Town and Country Planning (General Permitted Development) (England) Order 2015 and the Article and Schedule structure is different.
